Geospatial data is a commodity that is used every day by governments for policy development and execution, environmental management, disaster response, agriculture, health care, transportation planning, delivery of clean drinking water, land-records management, combating poverty, sustainable economic development, defence as well as food security. Geospatial data is indispensable element of effective governance, including E-government, transparency in government, good science, and better decision making. Simply put, government needs geospatial data in order to govern. Therefore, public sector data producers have an obligation to facilitate access to their national geospatial data assets. One special characteristic of geospatial data is, it can be shared and used for many other purposes than the one, for which, it was originally produced. To facilitate its efficient sharing and reuse, it needs to be properly managed. This is one of the reasons that many countries are developing National Spatial Data Infrastructures (NSDIs). NSDIs are becoming an essential element of each country’s Information and Communication Technology (ICT) plan. Well maintained NSDIs not only empower governments but also citizens and institutions as well.
